10 displayed at all times.

A further object of my invention is to provide a device of this character which is of simple and rugged construction and requires but slight effort to change the date displayed.

A further object of my invention is the provision of a device of this character which involves a filler member carrying a predetermined number of indicia-bearing disks and means whereby the disks are yieldingly urged into position to be displayed.

My inventive concept also contemplates the provision of a novel filter unit which may be manufactured and sold to the trade for the refilling of the device.

25 For a better understanding of my invention reference may now be had to the accompanying drawing forming a part of the disclosure wherein:

Figure 1 is a longitudinal sectional view of a preferred form of the device adapted to be embodied in or associated with any conventional fountain pen or pencil;

Figure 2 is an elevational view thereof;

Figure 3 Ba top plan view of the device illustrating the manner in which the indicia on the top disk is visible through the transparent plate;

Figure 4 is a transverse sectional view taken substantially along the line 44 of Figure 1;

Figure 5 is a similar view taken substantially along the line 5-5 of Figure 1;

40 Figure 6 is a fragmentary elevational view,

partly broken away to show hidden parts in section, illustrating a modified form of the invention; and

Figure 7 is a similar view illustrating portions 45 of the device shown in Figure 6 in separated relation.

In the embodiment of the invention illustrated in Figures 1 to 5 inclusive of the accompanying drawing is shown a tubular member 10 which 50 may be either the top portion of a fountain pen or the like or an attachment shaped for co-action with the upper end of any conventional writing instrumentality.

As shown, the member 10 is provided intermediate its ends with an inwardly extending annular flange 11 and from this flange to the top 12 of the member 10 the diameter of the bore of the member is increased to accommodate a sleeve 13. The sleeve 13 is designed to slide into or out of the member 10 and in itsinnermost position abuts an annular shoulder 14. The upper end of the sleeve 13 is formed with an annular flange 15 against which a pad 16 of circular disks 17 are pressed by means of an expansion spring 18 disposed between the pad 16 and the flange 11'.

A transparent plate 19 is secured in position over the ends of the sleeve 13 and the member 10 by means of a cap 20 having threaded connection as at 21 with the top portion of the member 10, the cap being apertured as indicated at 22 in order that indicia 23 on the uppermost disk 17 will be visible through the transparent plate 19. Each pad 16 comprises one disk for each day of a month, the disks bearing the appropriate indicia and being arranged in the proper sequence.

In the embodiment of the invention illustrated in Figures 6 and 7 the cap 20 has a sliding fit with the member 10 instead of the threaded connection shown at 21.

In this embodiment a removable ring 24 is utilized in lieu of the flange 15 and functions in exactly the same manner except that the removal of the disks is expedited by the provision of the removable ring.

It is proposed to provide filler units for the device disclosed herein, each of which would comprise one of the sleeve members 13 containing a pad 16 of disks 17 bearing the indicia appropriate to the consecutive days of a month.

To fill the device it is only necessary to remove the cap 20, insert one of the units into the upper end of the member 10 whereupon the spring 18 will enter the sleeve 13 and engage the pad 16, and then replace the cap upon the member 10. The member 10 preferably carries a conventional clip 25 for retaining the device in a pocket.

In use of the device it is necessary to remove the cap 20and the uppermost disk 1'? each morning or evening in order that the device may al-,

ways indicate the current date.

Although I have illustrated only certain forms which my invention may assume and have described those forms in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various modifications may be made therein without departing from the spirit of my invention or from the scope of the appendant claim.

I claim:

A calendar writing instrumentality comprising a tubular member formed intermediate its ends with an inwardly extending annular flange; a filler unit slidably mounted within the member, comprising .a sleeve containing a pad of indicia bearing disks, a cap removably associated with an end of the member; and a spring bearing against the annular flange and urging the disks toward the cap.

JOSEPH DILIBERTO.
